Vmax is reduced, as arranged Vh=Vmax by reducing Vh;
S104 improves the maximum restriction transmission rate Vmax of message, performs step S105;
Average response time is less than desired value, illustrates that opposite equip. has the ability to process more data message, can improve the maximum restriction transmission rate Vmax of message, to make full use of Internet resources;
Vmax is improved, as arranged Vl=Vmax by increasing Vl.
S105 flow process terminates.
In above-described embodiment, if by adjustment Vh and Vl, when still needing adjustment Vh and Vl after Vh and Vl satisfies condition Vh-Vl <=1, then Vh and Vl can be reset to its initial value, readjust Vmax.This situation generally occurs in network environment and changes, time the trigger condition of existing adjustment Vmax has been not suitable for existing network environment.
Above-described embodiment is described in detail below with a concrete application example.
Step 1, message is set according to current network conditions can reaches maximum transmission rate Vh=300bit/ms, message can reach minimum transmission rate Vl=0bit/ms, message maximum restriction transmission rate Vmax=(Vh+Vl)/2=(300+0)/2=150bit/ms;
Step 2, to opposite equip. send message;
Step 3, statistics opposite equip. are to the average response time sending message;
Step 4, judge whether this average response time is greater than desired value, if this average response time is greater than desired value, perform step 5; If this average response time is less than desired value, perform step 6;
Step 5, Vh is reduced to current Vmax, now Vh=150bit/ms; Vmax=(Vh+Vl)/2=(150+0)/2=75bit/ms; Judge whether Vh and Vl satisfies condition Vh-Vl <=1, if satisfy condition, perform step 7, otherwise return step 3;
Step 6, Vl is brought up to current Vmax, now Vl=150bit/ms; Vmax=(Vh+Vl)/2=(300+150)/2=225bit/ms; Judge whether Vh and Vl satisfies condition Vh-Vl <=1, if satisfy condition, perform step 7, otherwise return step 3;
Step 7, statistics opposite equip., to the average response time sending message, judges whether this average response time equals desired value, if this average response time is not equal to desired value, returns step 1.
